Amazing rare Card Ring 
Designed as 4 cards - diamonds, clubs, spades, hearts in a flower shape, with an almandine garnet in a rub over silver setting set between each card. The centre is set with a blob of silver (which they sometimes did) and it looks original.
 
Reeded gold shank which is probably a replacement
 
I was told this is a German ring circa 1800 ( I have a smaller french one which is circa 1750)
Face - 10.5mm x 10.5mm
 
Weighs - 2.5g
 
Size - 5.25
